The Big Bass Christmas Bash slot is Pragmatic Play’s 2023 festive edition of the fishing series, set on a frozen lake with a 5x3, 10-line grid. Under the snow it adds real changes: three routes into free spins, base-game rescue features and a choice of five bonus modifiers, with a 96.71% RTP and a 5,000x cap.

Free spins can start from three scatters, a nudge-and-respin on two scatters, or a hook that pulls a reel down.
When fish land without a fisherman, dynamite, a hook or a bazooka can place one to collect the cash.
A modifier from a list of five (more fish, more fishermen, more dynamite, two extra spins or starting at level two) is applied before free spins.
RTP is 96.71% with high volatility; the 100x bonus buy seen abroad isn’t offered in Great Britain.

Big Bass Christmas Bash: more than a seasonal reskin
Seasonal editions of popular slots are often little more than new artwork. Christmas Bash is different. It borrows the extra base-game features and pre-bonus choices introduced in later Big Bass titles and puts them on top of the core formula from Big Bass Bonanza. If you skipped it assuming it was just a Santa hat on the fisherman, it plays more like a fuller sequel.
The headline numbers are the same as the original’s RTP (96.71%) but with a 5,000x cap, the same ceiling as Big Bass Splash. The volatility is rated high by Pragmatic’s figures, though some slot databases list it as very high, a sign that bonuses can be streaky.
The frozen lake setting and symbols
The action moves to an icy, snow-capped lake. Pragmatic Play’s own description picks out snow ploughs, dragonflies and tackle boxes among the paying symbols, with fish carrying cash values and a fisherman who acts as the wild in the bonus. The palette shifts to cold winter colours to match.
Underneath, the grid is the series standard: 5 reels, 3 rows, 10 fixed paylines, paying from the leftmost reel. If you know the paytable layout of any earlier Big Bass game, this one reads the same way.
Three routes into Big Bass Christmas Bash free spins
Route
What happens
Result
Three or more scatters
Scatters land anywhere on the reels in one spin
At least 10 free spins
Two scatters plus nudge
Two scatters that can nudge down one position lock in place for a respin
A third scatter may land and trigger the bonus
Hook
A hook appears at random and pulls a reel down
Can reveal a third scatter
None of these routes changes the game’s overall return; they are built into the 96.71% figure. They do change how triggers look on screen, and they mean near-misses sometimes turn into bonuses. It is still worth remembering that a near-miss on a slot isn’t a sign that a trigger is close. Each spin is independent; see our glossary entry on the near miss.
Dynamite, hook and bazooka in the base game
In the earliest Big Bass game, fish landing in the base game with no fisherman are just symbols. Christmas Bash gives them another chance. Pragmatic Play says that when fish money symbols land without a fisherman, one of three random features may trigger to place a fisherman on the reels and collect the cash on show.
Dynamite: one of the three animations that can bring a fisherman onto the reels.
Hook: a second route to the same result, tied to the hook seen in the trigger feature.
Bazooka: the third variation; the outcome is again a fisherman who collects the visible fish.
The practical effect is more frequent small collections in the base game. That makes sessions a little less dry, but these collections are usually modest. They are part of the RTP, not an extra on top of it.
Five pre-bonus modifiers explained
Before the free spins begin, one of five modifiers is added to the round. Pragmatic Play lists them as:
More fish: extra fish money symbols are added to the reels for the round.
More fishermen: extra fisherman wilds are added, so collections happen more often.
More dynamite: the dynamite feature appears more frequently, helping fish and fishermen meet.
Two extra free games: the round starts with two more spins.
Start at level two: the round begins on the first retrigger level, with its multiplier already in place.
Each option shifts the shape of the bonus rather than its average value. Starting at level two concentrates value into a higher multiplier from the first spin; extra fishermen spread it across more collections. Exact effects are listed in the game rules.
Fisherman wilds, retriggers and multipliers
During free spins the fisherman is the wild. Each one that lands collects every fish value on the reels and adds to a counter. Every fourth wild collected retriggers the feature with 10 more free games and moves the multiplier up a level, starting at 2x. Later levels are shown in the game rules; in earlier series titles the steps continue to 3x and then 10x.
Here is what that means for a single collection at a 10p stake. Fish showing 5x, 10x and 25x add up to 40x, or £4. At the 2x level it becomes £8. Higher levels multiply it further, which is why the ‘start at level two’ modifier can be valuable when fish values are high. Read more in how free spins retrigger.
RTP 96.71%, volatility and a December budget
The 96.71% RTP matches the original and sits above the typical market figure. In plain terms, £100 of stakes costs about £3.29 on average over the long run. Check the rules screen at your casino to confirm the live version.
Christmas games tend to get played when money is already stretched, so it helps to fix a budget in advance. Suppose you set aside £20. At 10p that’s 200 spins; at 20p, 100 spins; at 50p, just 40. On a high-volatility game, 40 spins can easily pass without a bonus. The slots budget guide and a deposit limit set in your account are simple ways to keep festive play to what you planned.

How likely is the 5,000x max win?
The cap is 5,000 times the stake: £500 at 10p and £25,000 at the £5 UK limit for players aged 25 and over. Getting there needs high-value fish collected at a high multiplier level late in a long bonus, which is very rare. Many bonuses pay well under 50x. See what max win means.
Big Bass Christmas Bash in the UK: no 100x bonus buy
Pragmatic Play’s game page mentions a bonus buy at 100x the bet. That option isn’t available to players in Great Britain, so the UK version removes the button and leaves scatters, the nudge respin and the hook as the only ways in. Paying 100x for a bonus would also exceed many UK budgets: at a 20p stake it would cost £20 in one go.
The other UK slot rules apply: £5 per spin maximum from age 25, £2 for 18 to 24-year-olds, at least 2.5 seconds per spin, no autoplay, and a net position always on screen.
Big Bass Christmas Bash vs other festive and fishing slots
Fat Santa is the main non-fishing Christmas alternative, with a growing Santa wild. Big Bass Halloween is the series’ other seasonal edition, with a lower cap and slightly lower volatility. Browse more on our Christmas slots page.

Frequently asked questions
When was Big Bass Christmas Bash released?
Big Bass Christmas Bash was released by Pragmatic Play in 2023 as the festive entry in the fishing series. It arrived in the same year as Big Bass Amazon Xtreme, Big Bass Halloween and Big Bass Hold & Spinner, and it borrows newer series features such as base-game dynamite, hook and bazooka effects and a choice of pre-bonus modifiers. Our Christmas slots page lists other seasonal games, and Pragmatic Play slots covers the studio.
What is the RTP of Big Bass Christmas Bash?
The published RTP is 96.71%, the same as the original Big Bass Bonanza and Big Bass Splash. That works out at an average long-run cost of about £3.29 per £100 staked. A single session can be far above or below that, because the game is high volatility. Casinos choose which version of a game to install, so confirm the RTP in the game’s rules before playing. Read more in our RTP guide and what a good RTP is.
How do you trigger free spins in Big Bass Christmas Bash?
Three or more scatters in one spin trigger at least 10 free games. Two other routes exist: if two scatters land with room to nudge down a position, they lock for a respin in which a third can appear, and a random hook can pull a reel down to reveal a third scatter. Bonus buys aren’t offered in Great Britain, so these are the only ways in. Our scatter symbol glossary entry and what a slot bonus round is explain the basics.
What are the modifiers in Big Bass Christmas Bash?
Before free spins start, one of five modifiers is added: more fish, more fishermen, more dynamite, two extra free games, or starting the round at level two with a multiplier already active. Each changes how the bonus plays rather than its long-run value, because the maths is balanced across options. Starting at level two tends to concentrate value, while extra fishermen spread it across more collections. See our slot features guide and the reel modifier glossary entry for similar mechanics.
Is Big Bass Christmas Bash high volatility?
Yes. Pragmatic Play’s figures put it at high volatility, and some slot databases go further and list it as very high. Either way, expect stretches without much happening and most of the return coming from occasional strong bonuses. With £20 at 10p you get 200 spins; at 50p only 40, which may well pass without free spins. Losses are the likely outcome over time. Our volatility guide and high volatility slots page explain how to plan for this.
What is the max win on Big Bass Christmas Bash?
The maximum win is 5,000 times the stake. That’s £500 on a 10p spin, £1,000 on 20p, and £25,000 on a £5 spin, the highest stake allowed for UK players aged 25 and over. Reaching the cap needs a run of high-value fish collected at a high multiplier level, which is extremely rare. Most bonus rounds pay a small fraction of it. For background, read what max win means and what happens when a slot hits max win.
Can you buy the bonus on Big Bass Christmas Bash in the UK?
No. Pragmatic Play’s game page mentions a bonus buy at 100x the bet, but feature buys aren’t offered to players in Great Britain. UK casinos remove the option, so the bonus comes only from scatters, the nudge respin or the hook. At a 20p stake, a 100x buy would have cost £20 for a single bonus, which shows how quickly such features can use up a budget. See can you buy bonuses on UK slots and our bonus buy glossary entry.
Is Big Bass Christmas Bash different from Big Bass Bonanza?
Yes, beyond the snow. Christmas Bash adds base-game dynamite, hook and bazooka features that can place a fisherman to collect fish, a nudge respin on two scatters, a random hook trigger and five pre-bonus modifiers. The cap is 5,000x against the original’s 2,100x, while the RTP is the same 96.71%. The original is simpler and a little calmer. Compare our Big Bass Bonanza review with the fishing slots overview to see how the series has grown.
